Alternatively, you can wrap a piece of paper or string around your finger to fit as you would like your ring to. Then measure the length of the paper/string in milimetres (mm) and compare to the above size chart. Email me if you are having difficulty, but don't forget you can send it back if it doesn't fit (See terms & conditions)
